This study aimed to investigate the associations between perceived parental control, perceived parental modeling and parent-teen co-decision making, and fruit and vegetable (F&V) and sugar-sweetened beverage and junk food (S&J) consumption among Chinese adolescents, and examine whether self-efficacy mediates the associations. Data were collected in a cross-sectional survey of Chinese adolescents carried out in the fall of 2019. The questionnaires were adapted from the Family Life, Activity, Sun, Health, and Eating (FLASHE) Study. Ordinary least-squares regressions and a path analysis were performed to evaluate the hypothesized associations. The final sample included 3595 Chinese adolescents (mean (SD) age, 14.67 (1.73) years; 52.82% (n = 1899) males). Perceived parental control was positively associated with adolescents' F&V consumption, and was negatively associated with adolescents' S&J consumption. Perceived parental modeling and parent-teen co-decision making were both positively associated with adolescents' F&V consumption and negatively associated with their S&J consumption. Adolescents' self-efficacy was positively associated with F&V consumption and negatively associated with S&J consumption. These results suggest that serving as a positive role model, having adolescents participate in the decision-making process, and increasing adolescents' self-efficacy can be feasible and efficacious strategies to improve the nutritional quality of Chinese adolescents' diets.
